Data were collected by teams consisting of a supervisor, between 2 and 4 interviewers and a data entry operator. The number of teams varied from state to state depending on the sample size or number of EAs selected. The teams moved in a roving manner and data collection lasted for between 20 - 30 days for each of the post-planting and post-harvest visits. Additional details on the structure of the visits are available in Section 6.

5.2 Fieldwork Monitoring and Evaluation

As an additional aid to ensuring the good quality data, extensive monitoring was done of the field work Monitoring and evaluation guidelines and formats for fieldwork were developed. One (1) monitor was assigned to 1 - 2 states and all the states and FCT, Abuja were covered. There were three levels of monitoring and evaluation, the first and the third levels were carried out by NBS state officers and zonal controllers while the second level was carried out by the technical team which included individuals from the National Bureau of Statistics (NBS), the Federal Ministry of Agriculture and Rural Development (FMA&RD), the National Food Reserve Agency (NFRA) headquarter staff, and World Bank officials and consultants.

The monitors made sure that proper compliance with the procedures as contained in the manual were followed, effected necessary corrections and tackled problems that arose. The monitoring exercise was arranged such that the first level took place at the commencement of the fieldwork, and the third level not later than a week before the end of the data collection exercise. In-between these two, the technical team visited all the states of the federation and FCT, Abuja. While NBS state officers monitored in their state, the zonal controllers monitored in at least two (2) states (the zonal headquarters state and one other state of the same zone). The 1st and 3rd rounds of the monitoring exercise lasted for eight (8) days while the 2nd round by the technical team lasted for seven (7) days. Monitoring instruments were developed and discussed during both training of trainers and zonal training.
